SPEGIFICATEQN forming part of Letters Patent Ho. 459,918, dated September .22, 3.891.

Application filed May 6. 1891- Serisl Ila. 391,717 (1% model.)

To all whom it may concern.-

Be it known that 1, WILLIAM Simone, a citizen ot' the United States, residing at Indian spoils-in the county of Marion and Stztto'of Indianzuheve invented certain new and useful Improvements in Velvellfiechaniszn for Clot ets, Basins, and Like Situations, ot which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drswinp's, forming pnrt'of this specification.

My pres'e tinvention has relation more particularly to that class of valve mechanism commonly known as flushing-valve mechsnism, and designed to effect the cleansing of the bowls or basins in connection with which it is used by permitting a considerable volume of water to be quickly passed into and through the basin or bowl.

My invention consists-in the vsriousnovel features of construction hereinafter rl escrlbed, illustrated in the accompanying drawings, and particularly defined in the claims at the end of this specification.

Figure l is a view in side elevation of my improved velveineclinnism. 2 is an enlnrged view in vertical longitudinal sect-ion through the main portions of the mechanism."

A designates a stand-pipe, at the upper portion of which it reservoir A, the reservoir A being preferably a closed reservoir. The lower portion of the stand-pipe A is provided with a port or opening oz, to which Water will be admitted through the supply pipe or channel B, this pipe 01 channel communicating with a velve-chmnber C, to which water is admitted by an induction-port D. At the bottom of the stand-pipeA is formedsdischnrgo opening a", furnished with e valve-sent a Whereon will rest the egress-valve E, the stem 6 of this valve passing, preferably, through a. bearing 0, that is formed in piece or attached to the bottom of the stand-pipe A. To the lower end of the stem e is attached the operating-piston F, this piston working within a piston-chamber G, the bottom of which is preferably closed by a screw-threaded and removable cap g. \Vith the lower portion of the piston-chemlmr G communicates a pipe or channel ll, the opposite end of which conmeets with the valve-chamber Q and is proes the piston vided with the seat 7;, whet-eon rests the con trollin evelve K. This valve K pressed normally to its by nieens'of a coiled spring 16, that encircles the-stern 7: of the valve, and by preference this stem k is furnished with a spiral groove W, in which will work a suitable pin fixed to the cover 0'' of the valve-chambertlirough which the stem 7; passes. The purpose in thus providing the stem 7a with a spiral groove of steep pitch 7 engaged by a pin is to-permit the gradual lifting of the valve K from its seatby storminghsndle K. From the lower port-ion of the piston-chamber G lends a vent pipe or passage P, communicating, preferably, with the outflow-pipe B, and by preference this pipe or passage P is'furnished Wll-ll a valve 1), whereby the escape of water through he vent pipe or passage can be regulated. The

interior of the piston-chamber G is preferably formed with stops g to limitthe up ward movement the piston.

From. the foregoing description it will be seen that when the valve mechanism is in. the normalv position illustrated in the (lizl.W ings the Wate from the street-main or other source of supply will-pass into and till the valve-chamber C, the supply pipe or channel B, the stand-pipe A, and the reservoir A", and at such time the egress-valve E, resting, as it does, upon the seat a will close the dischargeopening a at the bottom of the stsnd-pipe it now it is desired to flush the bowl or basin, it is only necessary turn the handle K, thereby causing the valve to be lifted from the seat h of the pipe or channel ll, riitting Water to pass through the pipe or channel ll into the piston-chamber G liieneeth the piston F. It is manifest that inasmuch F is of considerably greater dinnieter and area than the egress-valve E the force ofivater upon the piston 15 will force this piston upwardly and will cause the egress-valve E to be lifted. from its seat. lifting of the egress-valve will permit the head or supply of Water Within the pipe A and reservoir A to pass from the bottom of the pipe A, and thence through the outflowpipe R to the bowl or basin. As soon as the handle ii" of the operntingw'nlve l; is released, the coiled spring: 7i: will return the valve it. to

This J its seat 71, thereby cutting oil" the supply 0E water through the pipe H into the pistonehainber. The force of water within the pipe A, and as well, also, the weight of the piston F, will cause a downward movement of the piston, which will continue until the egressvalve E is again firmly in position upon its scat In order to permit the water to tiow from the bottom of the piston-chamber',l have provided the vent pipe or passage I, and it is manifest that as the piston F moves toward its normal position the water behind such piston can escape through this vent pipe or passage as the piston G position. Hence it will be seen that the length of time during which the flushing operation will continue will depend upon the rapidity with which the Water is allowed to escape from beneath the piston F through the vent pipe or passage 1 and this extent of flush can be regulated by the adjusting screw p, which serves to control the pipe or passage P.

It Will be readily understood that the details of construction above set out may be varied widely without departing from the spirit and scope of my invention.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In appnraluscf the class described, the combination of a suitable flushing" pipe. or reservoir, a supply pipe or channel for admitting water thereto, an egress-valve for controlling the flow of Water therefrom, a piston for etiiecting ilic movement or" said egress valve, a chamber for said piston, and a valve for controlling the how of water into said piston-chamber, substantially as described.

2. In apparatus of the class described, the combination of a suitable flushing pipe or reservoir, a supply pipe or chan nel for adn1itting water thereto, an eerers-valve for controlling the flow of water therefrom, a piston for effecting the movement of said egress valve, said piston being of considerably larger diameter than said valve, a chamber for said falls to its normal piston, and a valve for controlling the flow ofnel to permit the escapement of water therefrom, substantially asdescribed.

l. In apparatus of the class described, the combination of a suitable flushing pipe or reservoir, 3. supply pipe or channel for admib ting water thereto, an egress-valve for controlling the flow of Water therefrom, a piston for ellecting the movement o1": said egress valve, a chamber for said piston, a valve for controlling the flow of water into said pistonchamber, 'and a vent pipe or passage leading from said pistonchalnber to the outiloiwchaw nel to permit the escapeinent of water therefrom, and an adjusting device for controlling the escape of water through said pipe or parsage, substantially as described.

5. In apparatus of the class described, the combination of a flushing-pipe A, a reservoir A, a supply pipe or channel 1- communicating with said flushing-pipe A, a val vechanr her O, communicating with said supply pipe or channel B, an egress-valve E for obstructing the lion from said fillshingqiipe A, a piston 1, connected to said egress-valve, a pistonchamber G, an outflow port or passage ll, a pipe or channel ll, communicating with said piston-chamber G and with said valve-chainher (3, a valve li for obstructing the (low of Water into said pipe or channel ll, and a vent passage or channel P, leading from said piston chamber G, substantially as described.
